Abstract: In described examples, an integrated circuit (IC) includes first and second integrators, first and second weighted summers, first and second digital-to-analog converters (DACs), and a quantizer. First and second inputs of the first weighted summer are respectively connected to an output of the first integrator and an output of the second DAC. An input of the second integrator is connected to an output of the first weighted summer. An input of the second weighted summer is connected to an output of the second integrator. An input of the quantizer is connected to an output of the second weighted summer. Inputs of the first and second DACs are connected to respective outputs of the quantizer. An output of the first DAC is connected to a first input of the first integrator. A second input of the first integrator and a third input of the first weighted summer are analog signal inputs.

Abstract: The disclosure provides a detector that includes a pre-charge circuit. The pre-charge circuit receives a supply voltage. A pre-charged comparator is coupled to the pre-charge circuit and receives the supply voltage. The pre-charged comparator generates a transition signal at a transition node. A slope of the transition signal is greater than a slope of the supply voltage. A first diode connected transistor receives the supply voltage. A first capacitor is coupled to the first diode connected transistor. An inverter is coupled to the first diode connected transistor and generates an enable signal when the supply voltage is below a threshold voltage.
